ADJUSTABLE FOOT-BLOCK FOR BADIATORS.

Specification o! Letters Patent.

Patented Dec. 8, 1908.

Application led March 27, 1908. Serial No. 423,738.

To all whom it may concern:

Be it known that I, HERBERT E. JENNI- soN, a citizen of the United States, residing at Fitchburg, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Adjustable Foot-Blocks for Radiators, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is to secure an eiiicient foot-block for radiators by means of which they may be made level though the floor on which they are set is unlevel.

In use at present are some forms of adjustable foot-blocks, but in the majority of cases they have been found defective and plain wooden blocks have been substituted. These have generally been constructed so that it was necessary to adjust the block previous to placing the radiator thereon, as the adjusting tended to throw the leg off the supporting surface. To overcome this, a top plate has been constructed which is composed of a series of annular rings, the center ring being the lowest and each ring outside thereof being a little higher than the previous one. When the screw is turned to raise or lower the radiator, these rings throw the leg over the aXis of revolution and prevent any riding off.

The following describes the preferred embodiment of the invention.

Figure 1 is a side view of device complete. Fig. 2 shows a top view of same. Fig. 8 is a vertical section on 3-3 showing the internal arrangement of the parts. Fig. 41same as Fig. 1 but showing a form of top ate.

p Referring to the drawings, 5 is the base plate, having a threaded socket 6 to contain the screw bolt 7 attached to the upper plate 8, upon which it is supported.

Upon the lower plate and near its outer edge is a vertical annular ring 9 within which slides a similar ring 10 upon the upper plate. The advantage of these rings is to strengthen the socket and bolt and add to the appearance of the block.

Instead of having the top surface of the top plate flat, there are the rings 11, 12 and 13, each being a trifle deeper than the previous one toward the center, so that when we revolve the top plate 8 by gripping its outer rim 14 and unscrewing the bolt 7 by means of the same, these annular rings tend to throw the leg of the radiator toward the center ring 13 and thus over the axis of revolution instead of its riding off by the weight of the radiator coming at a point other than over the axis of rotation of the revolving upper plate. Instead of the rings 11, 12 and 13 above described, a cup shaped surface 15 might be used. on the upper plate as shown in Fig. 4.

The device above described is usually constructed of metal though a hard wood might be used.

What I claim as new and desire to secure by Letters Patent isz- In adl'ustable radiator blocks, the combination with a lower plate having a central threaded socket, of an upper plate having a central threaded bolt upon its bottom, and a series of concentric annular rings forming shoulders on its supporting surface, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HERBERT E. JENNISON.
